Each Cisco Aironet radio product is designed to perform in a variety of environments. Implementing the antenna system can greatly improve coverage and performance. To optimize the overall performance of a Cisco wireless LAN, it is important to understand how to maximize radio coverage with the appropriate antenna selection and placement. An antenna system comprises numerous components, including the antenna, mounting hardware, connectors, antenna cabling, and in some cases, a lightning arrestor.This wall mount indoor/outdoor path antenna with RP-TNC is a special type of antenna unique to data transmission. It works well and fits aesthetically into most work environments. Mechanically it represents small rectangles about 1/2 inch thick. They are designed to mount flat to a wall and seem to disappear into the wall in most environments. The radiation pattern is in the shape of a hemisphere. A typical application would be for coverage of an area where the transmitter is located on the side of the coverage area.
